Trade J.Goff QB for TE Kyle Rudolph?

J.Goff is my back up, I have asutin sefari jenkins as TE, but I can get TE Rudolph as my back up if I trade away Goff.I can drop TE T.Kroft then. I can pick up Jimmy Garoppolo from waivers, his schedule towards the end of the season look good.

Garoppolo schedule

week 14 vs houston
week 15 vs tenessee
week 16 vs Jax

I have Desean Watson as my main QB, I wont be using Goff as much.

Should I do the trade???
